Psychologist

Ability

Each night, you must choose a player: you learn their characteristic.

John is Adaptable. The Psychologist wakes up and chooses John. The Psychologist learns that John is Adaptable.
The Psychologist is malfunctioning. John is Adaptable. The Psychologist wakes up and chooses John. The Psychologist learns that John is Persevering.

As the Psychologist your ability will allow you to ascertain the characteristics of other players, this can be particularly helpful information if you can find players that have potentially high impact characteristics on the game, such as Trustworthy.
You can use your ability to ascertain if people are lying about their characteristics. Try asking a player what their characteristic is, and then check them with your ability during the night. Remember, just because a player is lying, doesn’t necessarily make them on the opposite team to you. They might have a good reason to lie.

Each night, wake up the Psychologist. Tell them to choose a player. Tell them the characteristic of the player they chose. Send them back to sleep.
